Strawberry preserves! Although, I love raspberry preserves too. Cherry is good also. Oh, and I LOVE apple (MINT flavored apple jelly, from Smuckers, which is also the source for all of the other jellies, preserves etc. that I buy--go Smuckers!!).

This is a tough question. I like them all. I feel it depends upon the peanut butter as well. Crunchy peanut butter for instance is better with grape where as smooth and creamy best complements peach. I never thought about it much but bread type may also be at play here. Rye for example would probably not be my first choice as a delivery medium but if restricted to rye bread I may not use jelly at all but rather some type of marmalade (in which case I could not have answered this poll as it did not provide “none” as a choice)

YUM! & i love those squeezable jelly containers cuz then you dont get jelly in your peanut butter jar or peanut butter in your jelly jar. that sucks.
a pb&j sandwich is nothing without a giant glass of ice cold milk. i need to add this to my list of all things awesome.
